如何实现存储过程返回数组对象

本篇内容主要讲解"如何实现存储过程返回数组对象"，感兴趣的朋友不妨来看看。本文介绍的方法操作简单快捷，实用性强。下面就让小编来带大家学习"如何实现存储过程返回数组对象"吧!

其实就相当于返回List里面放的对象数据，定义如下

1.创建存储过程对象

复制代码 代码如下:

CREATE OR REPLACE TYPE "T_ACCOUNT_MONTH"
as object(
ACCOUNT_ID NUMBER,
INIT_AMOUNT NUMBER,
DEBIT_AMOUNT NUMBER,
CREDIT_AMOUNT NUMBER
)

2.创建存数过程数组

复制代码 代码如下:

CREATE OR REPLACE TYPE "T_ACCOUNT_MONTH_TABLE"
as table of t_account_month

3.创建存储过程

复制代码 代码如下:

create or replace function account_month(tDate IN DATE)
return t_account_month_table pipelined
as
v_account_month t_account_month;
v_date DATE;
begin
v_date:=tDate;
IF v_date IS NULL THEN
v_date:=sysdate;
END IF;
for myrow in (
select d.ACCOUNT_ID,
sum(decode(sign(d.create_time-trunc(v_date,'month')),-1,
d.debit_unvoucher + d.debit_unposted +d.debit_posted - d.CREDIT_UNVOUCHER -d.CREDIT_UNPOSTED- d.CREDIT_POSTED_D,
0)) INIT_AMOUNT,
sum(decode(sign(trunc(d.create_time,'year')-trunc(sysdate,'year')),0,
d.debit_unposted+d.debit_posted,
0)) DEBIT_AMOUNT,
sum(decode(sign(trunc(d.create_time,'year')-trunc(sysdate,'year')),0,
d.credit_unposted+d.credit_posted,
0)) CREDIT_AMOUNT
from ACCOUNT_DAILY_VEIW d
group by d.ACCOUNT_ID
) loop
v_account_month := t_account_month(
myrow.ACCOUNT_ID,
myrow.INIT_AMOUNT,
myrow.DEBIT_AMOUNT,
myrow.CREDIT_AMOUNT
);
pipe row (v_account_month);
end loop;
return;
end;
